The tuners on this Kay Speed Demon are nearly 50 years old, and they're worn out. The old tuners are 6-in-line, but not Fender spacing. Matt Brooker shows how he's modifying the replacement tuners to fit the guitar.

Dan Erlewine needs to pull the tuner grommets/bushings from the peghead of this old Gibson. The lacquer is already damaged, and pulling the bushings can yank finish off too. Dan rigs a jig that holds the finish down while the bushing comes up.

Dirty tuners filled with dried gunk: Dan Erlewine's working on a guitar that's been sitting untouched for over fifty years. The tuners are too stiff to use, but he gets them going again by using heat, naphtha and an injection of lubricant. He makes a nifty little tuner-holder jig, too.

Six tuners lined up perfectly straight, and no chips in the finish.
The last step in building this beautiful electric guitar is installing the tuners.
Brazilian luthier Rod Gomes visited Dan Erlewine's shop to show how he does it.

Will you need to drill holes in your guitar if you put new tuners on it? How do you figure out which tuners are an easy fit, and which require more work? What about keeping the old tuners for resale value? We get questions, and Erick Coleman has answers.
